And Gate Recognition System for Short Range Targets

Being aimed at the weakness of short range target′s threshold value recognition system,the double passage And Gate recognition system was put forward on the correlativity of target signals and randomness of noise signals Through state analysis and inference of state transition probability,both the reliability and early burst probability of the system were obtained in theory

一种高可靠的开关电容PUF电路

提出了一种高可靠的开关电容PUF(RSC-PUF)电路,通过在开关电容PUF(SCPUF)内部嵌入一个测试电容及相应的控制电路,在其运行过程中自动测试每个PUF单元的电容偏差,根据偏差大小为每bit输出生成相应的可靠性标识值,外部电路可以由此挑选可靠的PUF单元输出构建数字密钥.在HJ 0.18μm CMOS(互补金属氧化物半导体)工艺下进行流片验证,结果显示:当被挑选的可靠PUF的比率为20.5%时,RSC-PUF的比特错误率达到1×10-8以下,满足密钥产生所需的可靠性要求;而32 bit RSC-PUF所消耗的面积与SC PUF相比增加了约74.8%,远小于纠错机制所需要的开销.
